Are there really different styles of BJJ depending on your school?
Obviously no two instructors will teach BJJ techniques in exactly the same way word for word.
But a triangle is still a triangle and an armbar is still an armbar regardless of where you train, isn't it?
If you train at a Carlson Gracie academy for a month, then train at a Gracie Barra academy for a month will the styles of BJJ be markedly different? What would those differences be?
